The Pocket-Sized Power Supply Tests Electronics Anywhere

If you're the type to hit up thrift stores or garage sales then you know that most used electronics don't have power supplies or batteries handy. Make Magazine shows you off how to build a simple pocket sized power so you can generate power anywhere you are.

You don't need much in the way of materials to get this to work, just a few capacitors, resistors, a perf board, and a 9V battery connector. When you're done, you'll have a tiny little power supply that you can fit in your pocket that you can use to test all the weird electronics you find on your shopping adventures.
